MACHINE FOR GRINDING GLASS, 81.0.

SPECIFICATION forming part of Letters Patent No. 342,935, dated June 1, 1886. Application filed July 16, 1885. Serial No. 171,760. (No model) To all whom, it may concern:

Be it known that we, OELEsTIN SEYER and EDMOND RICHARD, both citizensof the United States, and residents, respectively, of est Hoboken, Hudson county, New Jersey, and of New York city, New York, have invented certain Improvements in Machines for Grinding, Polishing, the following is a specification.

Our inyention relates to machines for grinding bevels and moldings on the edges of glass plates, for grinding grooves or lines in the faces of said plates, for producing ornamental designs on the faces of same by grinding or abrading, and for polishing glass.

Our object is to produce a convenient machine for this purpose, which may be operated by hand or other power, and wherein the rotary motion of the power-shaft may be converted into double alternate reciprocating motion, so as to operate both rotary and reciprocating grinders simultaneously, and wherein rotary motion of said shaft may be made to produce a continuous motion of the grinder through a circular or variable path, whereby plates having ornamental contours may be ground or beveled to pattern, or ornamental figures may be produced on the face of the glass in the same manner.

Our machine will be hereinafter fully described, and its novel features particularly defined in the claims.

In the drawings, which serve to illustrate our invention, Figurel is a plan of the machine, and Fig. 2 is an elevation of the end at the left in Fig. 1. These views show the machine when adapted for grinding in straight lines and with rotative and non-rotative grinders. Fig. 1 is adetached cross'section on line 1 1 in Fig. 1, and Fig. 1" is a plan view of the slotted coupling to the rack. Fig. 3 is an elevation of the lefthand end with the upper hinged part thrown back and the machine adapted for grinding or ornamenting in irregular or curved lines. Figs. 4 and 5 are views of the rotary continuous grinders and its 0perative mechanism detached, and on a larger scale. Fig. 4 is a plan of the under side, and

Fig. 5 a section on line 5 5 in Fig. 4.

Referring particularly to Figs. 1 and 2, A

is the substantial frame or table, and B is the bed of same, upon which the plate of glassX and Ornamenting Glass, of which is placed to be ground or ornamented. The glass may be fixed in position on the bed in the usual or any way. The bed is constructed to be moved up and down in the frame A,upon suitable guides at a a, and adj llStlDg-SCIBWS b b are employed to support, move, and level the bed.

C is a frame, which is hinged to the frame A at c c, and is capable of being turned back, as seen in Fig. 3.

D and E are two reciprocating bars, usually cylindrical, the former being secured at its ends in a frame, F, with which it moves, and the latter being mounted to play in bearings at d (l in the said frame F.

Rotativelymounted on the frame 0 are two grooved pulleys or sheaves, e e, the grooves in which are engaged by the bars Dand E on the opposite sides of the sheaves. As these bars always move (as will be described) in opposite directions and at the same speed, it will be seen that the sheaves e 6 provide rolling anti-friction bearings for the said bars. 111' the same manner two sheaves, g g, rotativel y mou nted on frame 0, are arranged between the bar E and'the rounded edge h h of frame F for the same purpose.

G is a bar arranged parallel with frame F, and mounted on parallel guides/i i, fixed in said frame F. Thus the bar G is capable of being moved laterally toward or from frame F, the adj ustment being effected by the screws jj and their nuts jj. G of course reciprocates with F, being attached thereto.

It will be seen that the hinged frame 0 carries the several parts D, E, F, and G, and they can all be turned back together on the hinges c, as seen in Fig. 3. \Vhen down in place, as in Fig. 1, this hinged part, taken collectively, rests with itsweight on the bed B, or the glass plate, and, if desired, it may be weighted to cause the grinders to press more or less heavily on the glass.

The bars D Gand frame F are all connected together, and may be designated, when c011- sidered collectively, as the reciprocating frame. This frame bears the reciprocating grinders, both rotative and non-rotative, as will be explained."

H is a rocking lever, which is fulcrumed at k on the frame C.

' I is a link, one end of which is coupled at Z to the bar G, and at its other end it is coupled at l to one end of lever H.

I is a link, one end of which is coupled at m 'to the opposite end of lever H, and the other end at mv to a sleeve or collar, 01, secured to bar E. When the lever H is rocked on its fulcrum k, the bar E moves in one direction, and the reciprocating frame, comprising bar D, frame F, and bar G, in the other direction. The lever H is rocked and the parts above described given a reciprocating motion in opposite directions by means of a crank-whee], 0, mounted rotatively on a stud or spindle, p, mounted in a cross-beam, A. The crank is coupled by a wrist-pin, q, to a link, J, the other end of which link is coupled at s to the end of the rocking lever H. The rotation of the crank-wheel 0 is effected through a bevelwheel, 1', fixed to crank 0, which intermeshes with another bevel-wheel, r, on a cross shaft, K, rotatively mounted on the beam A, and provided with a drivi ng-pulley, L, or a crank, to which power is applied.

In the bar'G are fixed by a set-screw, t, a non-rotative grinder, M, made up of several plates or parts, (numbered 1 2 3 4 in Fig. 1,) so that they may be set to suit the bevel or mold on the glass plate. This grinder is fixed in a mortise in the bar G. Holes u u are also formed in said bar to receive non-rotative grinders of various kinds or formsthat is to say, having their ends formed to correspond with the molding or grooving required in the glass. These grinders I usually make of steel, as such grinders are customarily made, and I employ emery and other gritty substances ordinarily used as an abrading material.

On the bar D is also mounted a grinder, M, to grind the other edge of the glass plate. This grinder is mounted on a bracket, 1), constructed to be set at any point along bar D, and the grinder itself may be also adjusted on the arm 12 of said bracket. The grinder M is merely a cast-iron block with a steel face of the proper shape, and emery, &c., is used as the abrading material. M and M are shown in position as when grinding a bevel on the edge of a glass plate. i

In order to provide for the mounting of rotary grinders on the bar G, I mount on said bar an angle-rack, N, provided with two rows of teeth, 10 and w, as best seen in Fig. 1, and.

connect this rack with the bar E by an arm, at, extending'to it from sleeve n. The'rack is thus caused to reciprocate with bar E, and in an opposite direction to bar G. The rack is kept up to bar G by keepers provided with rollers y y.

In order to allow for the adjustment of the bar G toward or from the frame F, the arm a: has a slotted attachment to the rack N, as seen best in Fig. 1". From this rack N rotary motion is given to the grinders, as will be now described. A shaft, z, is mounted horizontally in bar G, and on its inner end is fixed a pinion, a, which meshes with the teeth 10 of the rack.

In Fig. 2 the grinders On the outer end of shaft 2 may be mounted any kind of rotary grinder or cutter, b, as seen in Fig. 1. This grinder b is reciprocated bodily by the movement of bar G, and also rotates with shaft z very rapidly and in a direction opposite to that it would have if rolling along a plane.

Mounted to rotate vertically in bar G is a tubular socket, c, which bears a pinion, c", on its upper end, which meshes with a spurwheel, a", rotatively mounted on bar G.

Below and on the same axis with wheel 0 is a pinion, 0*, indicated by dotted lines in Fig. 1, which meshes with the teeth w of rack N. Thus rotary motion is imparted to the socket c by the reciprocation of the rack, and any desired form of cutting-tool may be set in said socket to operate on the glass below. The

tool I usually employ is rounded or conical on its lower or operative end, and is made of steel. It is designed to rouglr out the heavier portion of the cut, and the usual abradiug material is employed.

The coupling of the link J to the lever H by a slot, as shown, enables the extent of reci'procatory movement of the parts to be regulated.

The frame 0, and with it the parts it carries, may be set out or in over the bed by means ofthe attaching-arms d d of said frame, which may slide through apertures in the hingiug-blocks e e, wherein they are secured by set-screws f f, as shown.

In sockets x in frame A are set standards 0 O, which may be secured in said sockets by set-screws, as shown. These standards form a support for the cross-beam A, which has eyes in its ends, through which said standards pass. The beam may be set any convenient height on the standards, and secured in place by set-screws g g, as shown, or by some other convenient means. \Vhen the frame 0 and its attachments are to be turned back, as in Fig. 3, the standards 0 may be lifted out of their sockets, and when said frame is turned back the standards are replaced.

I will now describe the grinding apparatus for grinding the edges of glass plates .having any contour of curved lines, whether regular or irregular, and for grindinglines of curved contour on the faces of such plates.

Referring to Figs. 3, 4, and 5 most particularly, the stud p is mounted in the cross-beam A, and splined so as to play endwise,but not rotate. Its upper end is screw-threaded to receive a collared nut, 12', whereby the stud p is given a longitudinal movement. The crank-wheel 0 is rotatively mounted on the stud p and a fork, g, on the beam A, engages a circumferential groove in the boss of o, and prevents it from slipping down on stud p.

Fixed on the lower end of the non-rotative stud p is a pattern-plate, P, of any desired contour; but having a contour corresponding to the path in'which it is desired the grinding-tools shall travel. Fig. 4 shows this plate in the form of a square with rounded corners.

. grinder it It It.

Loosely mounted on the stud p, between plate I? and crank 0, is a boss, P, in which are adj ustably mounted guide-rods h h, usually fixed in place by set-serews, as indicated by dotted. lines in Fig. 4. These rods embrace the boss g on crank 0, which receives the crank-pin g. This boss serves as a driver for boss P through rods h It. On these rods are mounted slides z" i, to the outer ends of which are fixed the compound On the inner end of each slide is mounted an anti-friction roller, a, and on the rods between the inner end of the slide and bridge-clamp 0 are arranged springs 2*. The bridgeclamp serves as an abutment for the springs, and enables their tension to be regulated by the adjustment of said clamp along the rods h. bear against the edge of the plate P, and they are usually grooved to engage the edge of the same, as shown, to retain them in position. The springs p keep the rollers up to the plate I, and when the crank-wheel 0 is rotated,and the grinders 7c, Ste, carried around, the contour of the plate P will govern and determine the path that the compound grinder will follow.

In order to allow the compound grinder to assume the proper relative positions at all times, we make it up of parts, as shown, and connect these parts by a flexible strip, is.

In practice the elements of the grinder will usually be quite small, as will also be the rollers n,and more than two rollers and guiderods will usually be employed. The parts k k k of this grinder will'be made of metal, usually steel, and connected by a steel strip, and emery will usually be employed as abrading material. The form given to the faces of these parts will of course depend on the form of mold or bevel to be given to the glass. In Figs. 4 and 5 I have supposed this to be a plain bevel. The elevation in Fig. 5 shows the form clearly.

Fig. 3 shaws how this grinder is operated. The hinged upper part having been turned back and the standards 0 0 again set in place, the beam A is adjusted t1 the proper height for the grinders to operate on the glass plate X on the bed B. It is now only necessary to impart rotation to shaft K in order to effect the grinding.

By changing the character of the grindingtool, in a manner well understood by those skilled in the art, lines may be ground in the face of the glass plate, following the form determined by the pattern P. The parts It It", &c., of the compound grinder rest by their weight 011 the glass, and may be fed down by means of the nut 11, as will be obvious.

\Ve may say that,in order to effect the change of parts above described, the link J must be uncoupled from the crank-wheel 0 by removing the coupling or wrist-pin q, as will be understood.

For polishing glass with our machine it will The rollers n only be necessary to substitute polishing maglass,comprisinga frame, A, and bed B, to support the glass plate, a frame, 0, hinged to frame A, and provided with means, substantially as described, for adjusting it laterally over the bed B, and a reciprocating frame bearing the grinders and mounted to reciprocate in the frame 0, substantially as set forth.
